What is a Consumer Confidence Report?

A Consumer Confidence Report (CCR) is the annual drinking water quality report that community water systems must provide to the people they serve. It lists the contaminants detected in the system’s water during the year, where the water comes from, and how the results compare with federal limits. EPA’s revised CCR rule takes effect January 1, 2027, and the first reports in the new format are due July 1, 2027.

Consumer Confidence Report status

LARCH CORRECTIONS CENTER must publish a Consumer Confidence Report — the annual drinking water quality report covering calendar year 2026 — by July 1, 2027.

System facts

System ID (PWSID): WA5306461
System type: Community Water System
Population served: 705
Service connections: 496
Ownership: state government
Water source: groundwater (wells)

LARCH CORRECTIONS CENTER is one of 428 community water systems in Washington in the 501 to 3,300 people size category, serving 705 people from groundwater.

As of August 1, 2026, its federal record holds 82 entries between 1998 and 2005, all of which EPA lists as closed. Nothing has been added since 2005.

All 82 are monitoring and reporting requirements — the category that accounts for about four in five of all violations in EPA's national dataset — rather than findings about the water itself. The record involves volatile organic chemicals, synthetic organic chemicals, and the Total Coliform Rules.
